For more complete information on the monuments at Tikal, pick up a copy of Tikal – A Handbook of the Ancient Maya Ruins, by William R Coe, which is available in Flores and at Tikal. A book you're best off finding before you come is The Lords of Tikal, by Peter D Harrison, a vivid, cogent summary of the city's history. Guards at the ticket booth sell you a useful site map (Q20).
